Fast Camera Analysis of Plasma Instabilities in Hall Effect Thrusters Using a POD Method under Different Operating Regimes

open access: yesAtmosphere, 2020
Even after half a century of development, many phenomena in Hall Effect Thrusters are still not well-understood. While numerical studies are now widely used to study this highly non-linear system, experimental diagnostics are needed to validate their ...

Advanced laboratory for testing plasma thrusters and Hall thruster measurement campaign

open access: yesNukleonika, 2016
Plasma engines are used for space propulsion as an alternative to chemical thrusters. Due to the high exhaust velocity of the propellant, they are more efficient for long-distance interplanetary space missions than their conventional counterparts.

The water electrolysis Hall effect Thruster

open access: yes, 2022
This study proposes operating a Hall effect Thruster (HET) on the products of in-situ water electrolysis. Oxygen is supplied to the anode and hydrogen to the cathode to mitigating poisoning. In comparison to other alternative HET propellants water is non-toxic, low cost, highly storable, and allows synergies with chemical propulsion systems.

Single- and two-photon absorption laser-induced fluorescence spectroscopy in rare gases for gridded ion thruster diagnostics

open access: yesEPJ Techniques and Instrumentation, 2022
Methods based on laser-induced fluorescence spectroscopy are widely used for spatially resolved non-intrusive diagnostics of atomic or molecular densities and velocity distributions in plasma applications.

High Fidelity Multi-Objective Design Optimization of a Downscaled Cusped Field Thruster

open access: yesAerospace, 2017
The Cusped Field Thruster (CFT) concept has demonstrated significantly improved performance over the Hall Effect Thruster and the Gridded Ion Thruster; however, little is understood about the complexities of the interactions and interdependencies of the ...
